Important
Local electrical codes supersede any information found in
this manual.
Electrical connections must be made by qualified personnel and is their
responsibility for using the proper power disconnect along with the correct
size and type of wire and conduit that conforms to all their local electrical
codes when connecting the machine and transformer to the buildings main
power.
Wire sizes
The minimum wire gauge inside conduit requirements are:
•
MTS Insight 100 – 14 AWG
•
MTS Insight 150 – 12 AWG
•
MTS Insight 200 – 10 AWG
•
MTS Insight 300 – 8 AWG
Ground wire needs to be the same gauge wire or larger than those listed
above for the associated frame size.
Electrical Disconnect
The electrical box must have a power disconnect switch that is easy to
operate and easy to reach. It must also meet IEC 60947-1 and IEC 60947-3
standards.
Recommended circuit breakers would be ones that are of the thermal
magnetic type with characteristics suitable for large inductive loads (D-type
trip characteristic). If fuses are used it is recommended that they are of the
time delay type with dual elements. These recommendations should be
followed to avoid nuisance tripping.
For the Insight 200 and 300 the electrical box over current device must be
Branch circuit rated.
